SPECIFICATION forming partof ALetters Patent No. 748,125, dated December 29, 1903. Application iiled May 4, 1903. Serial No; 155,574. (No model.)

To @ZZ whom it may concern:

Be it known that I, ARTHUR WEBER, a citi,- zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain 4new and useful 11nprovements in Bronzing-Machines, of which the following is a specification.

Myinvention relates to bronzing-machines, and has forits principal object the provision of a simple, efficient, and inexpensive device for automatically feeding printed paper and other material automatically delivered from a printing-press to said feeding device into the bronzing-machine.

The invention consists in certain novel constructions, combinations, and arrangements l 1 ing-frame and mechanism for operating it.

Referring to the drawings, A represents a feed-tablel or superstructure supported in any suitable mannerfor instance, by means of the bronzing-machine B itself, as shown in Fig. 1. The said table or superstructure is slightly inclined at its outer end in respect to the top of the bronzing-cylinder B'. A lip or extension A is provided, which acts to deliver the sheets to be bronzed directly upon the cylinder.

Referring to Figs. 2 and 3, A2 represents slots or ways extending longitudinally of the table and in parallelism. Projecting through said slots or ways are the feeding hooks or fingers C, carried on a reciprocating carriage or slide-frame D, Fig. 4:, located below the table. Means are provided for reciprocating said frame as follows:

Referring to Figs. l and 4, E is a cam mounted upon some rotary part of the bronz ing-machine--for example, upon the same l shaft as the cylinder. d represents a pivotal cam -stroke lever, carryinga cam-rollerV d and under the tension of a spring d2 to keep its roller in engagement with the cam, said spring acting also to retract the lever when released by the cam. ingrod, which connects the cam-lever d with a throw-lever f, mounted on a rock-shaftf, aorded bearings in brackets g, which brackets also 'serve to support the feed-table. The cam-lever d and throw-lever f are provided with openings e forpurposes of adjustment of the connecting-rod e to vary the throw 1 of lever f.. The rock-shaftf' also carries a thro w-lever g', adj ustably connected to a conmeeting-rod h, which is centrally pivoted to the slide-frame, as at h'., It will thus be apparent that when the cam E is rotated its circular part when in contact with the roller d' will, through the lever mechanism, above explained, cause the slide-frame D to be retracted, and when the dead portion of the cam is in contact with the cam-roller the spring d2 or its equivalent will retract the cam-stroke lever,and thereby cause the slideframe to move forward to feed material to the bronzing-machine.`

Referring again to Fig. 3, F represents the tape-rollers for conveying the sheets or material to be bronzed to the feed-table. G repe represents a connect resents side guides, and I-I represents front guides, for directing the sheets to the cylinder. I represents overhangingngers, which may be adjusted, as at t', to various angles and the function of which is to force the paper or material to be bronzed down to the level of the feed-board. The side guides are adjustable by means'of the slotted blocks G and clamping-screws@ K represents a plurality of tape-lines, which when operating with soft paper prevent a current of air from throwing it from its position on the board. L represents a jogger or guide, which is acted upon by the operator to push the material to be bronzed against the lateral guides G.

IOO

modiications may be made in details without departing from the spirit and scope of same. Hence I do not limit myself to the precise arrangements of parts and construction here-V inabove described; but,

Having thus described the nature and objects of the invention, vwhat I claim as new, and desire to secure by Letters Patent, is-'- 1. In a bronzing-machine the combination of a feed-table having slots lengthwise thereof, a reciprocating carriage beneath said table and having feeding-lingers passing through said slots, a connecting-rod h having one end attached to said carriage and at the other end a throw-lever g', a rock-shaft f for saidv lever, a second throw-lever f upon said shaft, a connecting-rod e having one end pivoted to the leverl f, a rocking cam-lever d pivoted at one end, and united to the opposite end of the rod e, and a coil-spring d2 secured also to the end of the cam-lever, with a cam E operating upon the rocking cam-lever d, substantially as described.

2. In a bronzing-machine the combination of a feed-table having slots lengthwise thereof, brackets g for said table, a reciprocating carriage having feeding-fingers through the slots of the table, a rock-shaft mounted upon the brackets g, two throw-levers mounted upon said rock-shaft, each throw-lever having av connecting-rod adjustably mounted thereon, a pivoted rocking cam-lever having its free end adjustably connected with one of the connecting-rods and also attached to one end of a coiled spring, with a cam operating upon the rocking cam-lever substantially as described.

3. In a bronzing-machine the combination of a feed-table having slots lengthwise thereof, guides parallel with said slots and adjustably secured upon the table, brackets for said table, a reciprocating carriage having feeding-ngers passing through the slots of the table, a rock-shaft mounted upon the brackets of the table, two throw levers mounted upon said rock-shaft, each throwlever having a connecting-rod adjustably mounted thereon, a pivoted rocking camlever having its free end adjustably connected with one of the connecting-rods, and a coil-spring having one end attached also to the free end of the cam-lever, with a cam operating upon the side of the cam-lever, substantially as described. l

In testimony whereof I affix my signature in presence of two witnesses.

ARTHUR WEBER.
